The United States will celebrate it’s Semiquincentennial anniversary in 2026. That’s the Nation’s 250th Birthday starting back with the signing of the Declaration of Independence in Philadelphia on July 4, 1776.

Using social media and through this website, you will have your opportunity to weigh in on the Top 250 historical events that have shaped the USA’s national identity.  These historical events range across: 

  • Political & Military
  • Liberties & Freedoms
  • Technology & Innovations
  • Science & Exploration
  • Arts & Entertainment

There are numerous commemorations being planned for this huge milestone and #USATOP250 is assembling a list of the Top 250 historical moments that have shaped our great nation to inspire future generations. The list is being developed with input from historians, academics, and – most importantly – the American people.
